Does everyone remember the movie eurotrip? If not, there's a scene in there where our three young heros decide to visit a nude beach. Hot chicks. YAY! Only not. Instead there is just a sweaty herd of fairly out of shape nude men. "so.. many.. penises" is the line uttered. Yeah, that was basically my experience at the gym.
Having freshly sold my soul to the corporate behemoth I decided to at least use some of the perks and try out the Pro Club health center. Nice place, 4 pools, lots of weight equipment - it's nice to have a proper gym. The locker room is pretty posh but there isn't a shy guy in the place apparently. And you have to remember that while the club is used by professional athletes it's also used by the legion of microsofters. Generally speaking, as an average, microsoft employees aren't really in the best of shape either. Really skinny or incredibly fat they all seem to share a desire to strut.
I've got no problem displaying my wares, going commando, dangling some tackle, whatever. But when you're in a narrow aisle of lockers, a guy is using the locker behind you and a fat hairy naked man has to squeeze - litterally squeeze - between you to get to his area it's a little... unpleasant.
I hope I've fully captured the experince for you.
